Volute Shutter cleaning

[E. von Hoegh]

E,

Thanks. I saw the möbius oil on amazon also (but not from a "prime" seller so I'll use your source).

It's important to use an oil which doesn't creep away from the pivots. The Hoppe's oil will creep. A very light molybdenum grease is good for points where (for example) a spring end bears and rubs on some other part.
Lubricants have improved drastically since these old shutters were made, I have two old Compounds from before the War To End All War, (WWI) specifically 1908 and 1913 - after overhaul they are as accurate as new modern shutters.

Edit - I have no connection (beyond being a happy customer) with the supply house I posted the link to.

I've recently bought an utterly sluggish Volute, and the blades look very metallic, to me. And probably with oil in it. Disassembled the shutter and cleaned the piston, but to no avail. And even on one part of the blades there's a tiny space leaving a light leak.
